If a number is raised to a negative power, is the answer always negative? Report Abuse. Raising a number to a negative power does not necessarily mean it is negative. The negative means that you are raising the reciprocal to that power. In other words 2 raised to the negative 2 power is the same as 1/2 raised to the positive 2 power. So the answer is 1/4. Likewise, 2 raised to the -3 power is 1/2 raised to the +3 power which is equal to 1/8. Note that a positive number raised to any power (whether positive or negative) will always be positive. Hope that helps.

Negative Exponent: Definition & Rules Exponents are numbers that are written as a superscript. The exponent tells a mathematician how many times a certain number should be multiplied to itself. The word exponent is from the Latin expo, meaning out of, and ponere, meaning place. The first recorded modern usage of the concept was in the 1500's.

Negative number For example, −3 represents a negative quantity with a magnitude of three, and is pronounced minus three or negative three. To help tell the difference between a subtraction operation and a negative number, occasionally the negative sign is placed slightly higher than the minus sign (as a superscript).

Zero Exponent: Rule, Definition & Examples The zero exponent rule is one of the rules that will help you simplify exponents. Let's first define some terms as they relate to exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent, or power.

Square root sign Every positive number A has two square roots: positive and negative ±√a . Although the principal square root of a positive number is only one of its two square roots, the designation the square root is often used to refer to the principal square root. For positive A, the principal square root can also be written in exponent notation, as A 1/2. But there are more roots than just square roots! We can say that the Nth root of a number X is a number R which, when raised to the power of N, equals X and its denoted like Rⁿ = X.

- Confidence votes 242. Whole numbers less than zero A negative integer is a negative whole number that is the opposite of a counting number. When we count, we start at 1 and count 1, 2, 3, etc. Negative integers are the opposite of those numbers: -1, -2, -3, and so on.

- 1 Example C: f(-x) = 7(-x)2 + 5(-x) + 3.  Again, look at the exponents, as well as the plus and minus signs. Even exponents will result in a positive x and odd exponents result in a negative x. A negative sign multiplied by a plus sign will turn the plus into a minus sign, and vice versa.

- Essentially, an exponent that is zero is equal to a variable to the power of an exponent times a variable to the negative power of the same exponent. For instance, x 2 times x-2 is equal to x 2 divided by x-2. Any number divided by itself is equal to one. Zero to the power of zero is a special case, however.

- No, it will be a positive. Subtracting a negative number is the same as adding its negative value, which is a positive number. 4 - (-3) = 4 + 3 = 7 Other examples For 5-(-7), … when there is a negative of a negative, you cross out the negatives and put a plus in their place.See 5+7 and then you solve the problem, 12. negative minus a negative turns the latter into a plus positive, for example -6 minus -3 would be : -6 ++ 3 = -3. A minus negative always turns into a plus positive... To get more Specific: Suppose x and y are two POSITIVE numbers so that-x and-y are negative.

- When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, bn is the product of multiplying n bases: b n = b × ⋯ × b ⏟ n {\displaystyle b^{n}=\underbrace {b\times \cdots \times b} _{n}} The exponent is usually shown as a superscript to the right of the base.

- As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form. A positive exponent shows that the decimal point is shifted that number of places to the right. A negative exponent shows that the decimal point is shifted that number of places to the left.

How to Write Numbers in Scientific Notation To see an exponent that’s negative, write .00000031 in scientific notation. 1  Move the decimal place to the right to create a new number from 1 up to 10. 2  Determine the exponent, which is the number of times you moved the decimal. 3  Put the number in the correct form for scientific notation.

- Enter negative exponents by first typing an equal sign, then the base number and then the exponent. For example, 7 to the negative third power would be typed in as =7-3. Enter negative exponents in another way by typing in the equal sign again first but then using the POWER function of Excel.

- Then the number you're taking the square root of is zero since 0 * 0 = 0. That covers the whole number line, so any square root you can find on the real number line must be the square root of a positive number or zero. It's impossible for it to be the square root of a negative number. This is why in the context of real numbers we say that you cannot take the square root of a negative number.

If a number is raised to a negative power, is the answer always negative? If you raise 2 to the -3 power, it will be 1/8. e.g. Raising a nonzero number to the −1 power produces its reciprocal. Thus: Raising 0 to a negative power would imply division by 0, and so is undefined. A negative integer exponent can also be seen as repeated division by the base.

What is a Negative number minus a Negative number? A negative number minus a negative number is always positive because while adding or subtracting a negative number, we keep it in brackets.If there is a minus before the brackets, when we remove the brackets,minus and minus multiply to become positive.For Ex. 12-(-5) = 12 -x- 5 = 12+ 5 = 17. negative number minus a negative number is always positive because while adding or subtracting a negative number, we keep it in brackets.

- That number is written in scientific notation. There is one digit to the left of the decimal point -- 2 -- and it is not 0. In general, a number written in scientific notation will be multiplied by 10 raised to an exponent.. 2.345 × 103 2.345 × 10−3. Without going into the details of what the exponents 3 and −3 actually mean, we can state the following : A positive exponent means to multiply by a power of 10.

Negative Exponents Anything to the zero power is 1, so 0 0 = 1. Zero to any power is zero, so 0 0 = 0. As far as I know, the math gods have not yet settled on a firm definition of 0 0 — though, to be fair, an informal consensus seems to be building that the value should be 1, and just about any programming language will spit out the value 1.

3. Simplest Radical Form n-th root of a Positive Number to the Power n. We met this idea in the last section, Fractional Exponents. Basically, finding the n-th root of a (positive) number is the opposite of raising the number to the power n, so they effectively cancel each other out.

- A negative number is a number $x$ such that $x+y=0$ for some positive number $y$. In other words, a negative number is an object whose sum with some positive number equals the additive identity. A similar approach can be used to define other mathematical objects: $ 1 x=0$ is an object such that $a+x=a$. $ 2 x=\frac{1}{a}$ is an object such that $xa=1$.
